'MEASURINGAN-D FILLING DEVICE.

. iA pplication filed. November 'This invention "relates 'to :improvements in" 'measurii1g='andifilling devices and has for'its primary object, the provision of a means .for 1automatically shutting oil vthe flow of :liquid to [a :tank when the liquid thereinreaches a predetermined level.

"The type ofnmeaisuring and. filling tanks noWin use depend on a so-called float valve to obtain. the correct: alevel iand quantity: of liquid in atan'k. 'The -float valvezadjusted for i a particular I level will keep the *same constant only it thexpressure of the liquid supply-is-constant. Assoon as the pressure goes 'bGlOW the: pressure *at' which the float- VEElVG WELS adjusted; the iliquid level in the tank Will be lOWBI asv the float i of the float valve will close the valve tight against its seat soonerwand vice versaa :A number of patentees have tried to overcome .thisdeficieney of the" float valve by providing overflows, overflowing chambers :or double float valvesp oneto regulate the level and the other to regulatethe pressure. However, all 01h :themeitherliinvolve' a loss of liquid or are so complicated that Fthjey are not dependable. l-"My inventionhis designed to overcome these objections; as the liquid level once determined. in the tank? willalways remain the same regardless. 0t: any change in pressureiunder which the liquid :is delivered to the measuring "tank.

be composed of a -t plurality of separate tanks Without 'in any Way "departingfrom the spirit of my "invention.

Depending? from the bottom of each tank B is: a'casingror'ehamber 1 having communioation with the: tank B through a; passage Way or 'opening 2. Theitop ofi thei casing Which surrounds the opening istormed'to provide 1 a valve seat 2; and "vertically. movable within the oasing iswai float valve or buoyant member- 8 provided-With a valve disk at forco-action with the seat-'2. The sides of the float valve are providedvmvith spaced radially arranged fins 5 forkeeping the Walls of theifloatvalve in spaced relation With the innenvertical Walls of the casing, and to guide the same lin -its vertical rmovement whereby liquid may :pass between the float Valve in the Walls-ofthe casing- Without choking the flovv. iTheicasing or chamber: is provided witha lower section 6 bolted orrotherwise secured to. the casing and in \Which is provided an inwardly projecting lug 7 for preventing the. float valve from: seating against the ilovver Walls Whnin-i a- ?liquid is. being discharged from. the ta Mounted Within each tank B adjacent. the top andbottom thereof, are tbraek'ets .8 which act asif guides or. bearings! ifor? a slidable float rod 9 having. a; globular float '10 adj ustablymounted thereon. 1 A. 2 collar 1-1 is formed on the rod: adjacent its lower: end for limiting the movement -of; the slower end-of the rod which extends through the passage 2, and normally p'revents the-float valve fromco acting With the seat 2 \to-alloivualiquid under pressurev to freely-:pass from the chamber to the 'tank- 13. r The float 10 has an-opening passing therethroughiin which is mounted a .light (ferrule 10 which is ifixedlyzmounted in the -W&llS of the =opening and serves as a bearing which may be removed'and replaced uWhen ,-Worn. The float 10 carries collars .from *Whl-Ghe set screws l2ipass for elampingftthe float inv an adjusted positiony-upon the rod for regulating the desired liqhidlevelrat which the device is adapted to operate for shuttingoif the flow of liquidxfronr the Hchamber 1? to the tank B. AItrimight bermentioned. that the float l0-and the rod 9icombinedare-of such Weight asito overcome the buoyancy ofrthe floatv'alve 3,:as it is not necessary forthe' same to exertanyotherpressureuas I inlthe ordinary. type of float valve.

The lower section 6 above referred to is provided with a threaded nipple 13 to which a three way valve 14: is connected. A l1qu1d supply pipe 15 connects with one side of the valve 1 1 while a discharge pipe 16 connects with the opposite side, and interposed between. the inlet and the discharge pipes is a rotatable plug 17 with the usual passage ways 18 therein for establishing and disestablishing communication between the supply pipe and the chamber, between the outlet or discharge pipe and the chamber and for completely shutting off communication between both the inlet and discharge pipes and the chamber. Connected with each plug 17 is a lever 19 and journalled 1n bearings 20 carried by the structure A is a rocker shaft 21 having an operating arm or handle 22 fixedly connected at one end thereof. Each lever 19' of the respective valves is operatively connected with the rocker shaft 21, by means of an arm 23 fixed to the rocker shaft and joined with the lever 19 by a pin and slot connection 2 1. By actuating the handle 21, movement may be imparted to all of the valves simultaneously for obtaining a correct setting of the valve plugs.

In operation, the three way valve 14: is set to connect the liquid supply with the chamber 1, at which time the discharge pipe is closed. The float 10 and rod 9 are at their lowest position, therefore holding the float valve 3 off the seat 2 to allow the incoming liquid to pass about the valve 3 into the measuring tank B until the level of the liquid in the tank reaches the float 10. As the float 10 rises, it moves the rod away from the float valve 3 until the said valve co-acts with its seat 2 at which time the flow to the tank is automatically shut off. As the float valve nears its seat the incoming liquid is gradually choked which creates a pressure against the float valve for positively seating the same, so that no liquid may pass to the tank B. When the rocker shaft is actuated to move the plug to a position for closing communication between the liquid supply and the chamber, and for establishing communication between the chamber and the outlet, the liquid pressure in the chamber is released as the liquid will be discharged which causes the float valve to automatically drop from its seat whereupon the static head' of liquid in the tank is free to pass out until the tank is entirely empty, at which time the valve may be reset for filling purposes.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction nor to anything less than the whole of my invention limited only by the appended claims.

lVhat is claimed as new is 1. In a liquid measuring device, the combination of a tank, a chamber, a passage connecting said tank and chamber, a float valve movable within said chamber, and a buoyant element within said tank movable independently of said float valve, and engageable therewith for holding said float valve out of closing position with said passage for permitting a liquid under pressure to pass through said chamber and into said tank, and for automatically releasing said float valve by the raising of said buoyant element when the level of liquid in said tank reaches a predetermined level for allowing said float valve to close said passage.
